Petoi Bittle stem robot dog

Petoi, the maker of futuristic robotic pets, today launches the Bittle STEM kit, a lower cost version of its palm sized robot dog that can help teach tech enthusiasts, young and old, about robotics and coding. Small but agile, Bittle can be programmed to walk, do tricks and roll around just like a real dog. Differing slightly from Bittle V1, the STEM kit contains plastic-gear servos instead of metal making it lighter and more flexible with different movements.

The Bittle STEM kit is available at from £223 ($269, RRP), but in the run up to Christmas, it will be available at a promotional price of £180 ($214). The Bittle STEM kit will also launch on Amazon UK mid-December.

The Petoi Bittle STEM kit is ideal for kids and adults with an interest in STEM, coding and robotics. It’s also perfect for those who just want to have fun and play with a robot pet companion. Bittle operates on OpenCat, an open-source quadrupled robot platform that offers endless programming and customisation possibilities. Educational, users can learn coding as they teach Bittle to run, jump, roll over, sit and lay down, just like a real dog.

Users bring the Bittle STEM kit to life by assembling its puzzle-like frame which is made up of plastic 3D interlocking components. The bionic construction of legs rather than wheels means that Bittle is able to move more freely over unstructured terrain. With a simple and beautiful design, Bittle can be easily configured and controlled using Petoi’s official mobile app, the included remote control or a number of different programming options. Users can also program Bittle to do tricks with Petoi Desktop App’s Skill Composer.  Petoi plans to release a free C++ four-legged robot curriculum by mid December.  Bittle is a great STEM learning tool and perfect for anyone interested in robotics and programming.

Evolving with an open-source gene, Bittle is built on Petoi’s OpenCat open-source platform which was first launched in 2018 by Petoi’s founder Professor Rongzhong Li specifically for quadrupled robots. Bittle’s dynamic manoeuvrability and behaviours are features typically seen on luxury robots but Petoi’s technology is now making it accessible to everyone.

With a customised Arduino board coordinating all instinctive and sophisticated movements, users are able to clip various smart sensors onto Bittle or mount a Raspberry Pi or other AI chips through wired/wireless connections to inject perception and artificial intelligence capabilities.

Features include:


  • OpenCat framework

  • Arduino compatible motion controller & wireless connectivity

  • Impressive running speed and agility

  • Interlocking plastic frame

  • Shock reduction joints

  • Programmable gaits and behaviours
